There is more to it than this but:

//initialise firebase
firebase.initializeApp(firebaseConfig);
var auth = firebase.auth();
var db = firebase.database();

All data is returned by Firebase

auth.onAuthStateChanged(function(user) {
  if (user) {
    // User is signed in.
    getData();
  } else {
    // No user is signed in.
  }
});

function getData() {
var dbRefObject = firebase.database().ref().child(ProjectBucket +"/"+ uid);
dbRefObject.on('value', snap => { window.AppInventor.setWebViewString(JSON.stringify(snap.val(), null, 3)); }); 
}
